A novel open-loop antenna with a coupled-line gap for application as an internal laptop antenna for GSM/DCS dual-band operation is presented Owing to the use of the coupled-line gap, the proposed antenna can operate both as a half-wavelength loop structure at 900 MHz and a one-wavelength loop structure at 1800 MHz The antenna is easily printed on a dielectric substrate with a low cost and is then integrated to the supporting metal frame of the laptop display to achieve a compact size of 9 mm in height and 70 mm in length, making it very promising to be embedded within the casing of the laptop as an internal antenna Design considerations of the proposed antenna are described, and experimental and simulation results of the constructed prototype are presented Effects of the coupled-line gap on the dual-band operation of the proposed antenna are also analyzed © 2007 Wiley Periodicals, Inc Microwave Opt Technol Lett 49: 680–684, 2007; Published online in Wiley InterScience (wwwintersciencewileycom) DOI 101002/mop22224read more
